TOOL-HOLDER FOR BLOW-TORCHES.

Application filed September 18, 1316.

To all whom it may concern Be it known that we, W'ILLIE PRUESSING andCARL PRUnssrNo, citizens of the United States, residing at Syracuse, inthe county of Otoe, State of Nebraska, have invented certain new anduseful Improvements in Tool- Holders for Blow-Torches; and we do herebydeclare the following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itappertains to make and use the same.

This invention relates to blow torches, and has particular reference tothe class of blow torches in which gasolene is used as a fuel.

It is the object of the invention to provide an improved tool holderadapted for readily detachable connection with a heater substantially ofthe class set forth, whereby to support the tool in position for properheating.

Nith the above object in view and such other objects as may hereinafterappear, our invention will now be fully set forth and described,reference being had to the accompanying drawings.

In the drawings,

Figure 1 is a side elevation of the torch,

Fig. 2 is a front elevation,

Fig. 3 'is a plan view,

Fig. 1 is a detail sectional View of the air inlet valve,

Fig. 5 is an enlarged elevation of .the burner, and

Fig. 6 is a sectional view through the burner.

Referring more particularly to the drawings, 1 indicates a tank intowhich gasolene is put, a suitable inlet port 2 being provided for thepurpose. The tank 1 consists of a cylindrical shell through the top andbottom of which extends an axially located tubular column 3, said column3 being open at its upper and lower ends so that a clear air passage isprovided vertically through the tank. The tank is furthermore providedwith a plurality of smaller columns 4 disposed near the periphery of thetank and extending substantially parallel to the column 3, the columns 3and 4 providing a suitably braced and rigid structure.

To one side of the tank 1 is secureol a rectangular boxing 5 whichprovides a support for a handle 6, the lower end of the latter beingsecured to the lower end of the boxing, and the upper end of the latterbe- Specification of Letters Patent.

ing looped through a strap 7 secured transversely across the boxing Theboxing 5 furthermore provides a support for a pair of sockets 8 securedto the sides of the boxing into which sockets the lower ends of atwo-legged iron support 9 are stepped.

Projecting from the top of the tank 1 and having a pair of openings invertical alinement with the openings in the sockets 8 is a plate 10, thele s of the support 9 extending through the openings in the plate 10 andbeing thereby supported at its intermediate portion. Secured to theopposite side of the tank 1 is a second pair of sockets or steps 11 intowhich the lower ends of the legs of the forward support 12 are received,and plate 13 secured to the top of the tank 1 having openings receivingthe intermediate portion of the legs of the support 12.

The top of the support 9 is bent downwardly Above the handle 6 and theboxing 5, the

tank 1 is provided with an air pipe 15, to which is coupled an air checkvalve 16 which preferably of a well-known type, so that a practical anduniversal connection for any ordinary hand pump, such as is used inconnection with automobiles and bicycles is provided. The check valve 16extends outwardly over the handle 6 in position to conveniently receivethe end of the rubber connecting hose or tube of the air pump so thatthe latter may be kept in continuous connection withi the torch throughthe use of the latter, but may be readily disconnected when the latteris stored away or not in use.

At the front of the tank, and issuing from the lower portion thereof, isthe gasolene pipe 17, which is bent upwardly into close relation to thefront of the tank, and lies between the legs of the front iron support12. At the top of the tank the gasolene pipe 17 is bentforward and hasits end carrying a coupling nipple 18 which in turn supports the stem 19of the upright tubular burner which stands forward of the front supportas seen in Fig. 1.

The burner 20 is of the retort type and consists of an annularcasting'21 which constitutes the upright burner body, a tubularprojection 22 below the bottom of the body providing a means for theinjection of the gaseous mixture into the body. One side of the castingis provided with an offset chamber 23 which, at one end, has an elbow24: into which the stem 19 is threaded. The opposite end of the chamber23 is provided with a threaded port to which is secured a downwardlyextending pipe 25 whose lower end terminates in the needle valve casing26. ,Below the casing 26 is a further projection 27 from one side ofwhich extends the nozzle 28, the latter lying below the lower end of theprojection 22 in order to inject the gaseous mixture into the burner.The needle valve casing carries the usual needle valve stem 29 wherebythe flow of the gasolene may be adjusted. It will be noted'that thecasting 23, the elbow 24 and the pipe 25 provide for the preliminaryheating of the gasolene before it passes through the. needle valve, andthence to the burner. In order to provide for the perfect action of theburner in cool weather or under other unsatisfactory circumstances, thelower portion of the burner together with the needle valve casing isinclosed in acasing 30 which extends from the base of the burner body toa point well below the needle valve and the nozzle 28, the casingconsisting of a tubular structure open at its lower end in order topermit the proper feeding of air to the burner and having openings inits sides through which the stem 19 and the needle valve stem 29project.-

From the foregoing description, it is ob vious that we have constructedan improved form ofgasolene blow torch which is particularly adapted forheating soldering irons, and that the details of its construction renderit a peculiarly handy and efficient device. of the burner and itsrelationship to the The particular arrangement vpipe leading out of thetank at the opposite side and carried upward and bent forward, and anupright tubular burner to which the gas pipe delivers; plates securedupon the tank at front and rear and each having two openings, socketssecured to the wall of the tank below said plates and in line with theirrespective openings, arear support having downwardly diverging legspassing through the openings in the rear plate, astride the air pipe andinto the sockets, its upper end having a seat for the shank of a tool,and a front support having downwardly diverging legs passing through theopenings in the front plate, astride the gas pipe, and into the frontsockets, its body above said plate being bent forward and its topprovided with a seat'disposed in rear of said burner and adapted tosupport the head of a tool. 1

In testimony whereof we affix our signatures, in the presence of twowitnesses.
